REVOLVING SWING.

SPECIFICATION forming part of Letters Patent No. 554,215, dated February 4, 11896. Application niet May si, 1895.l serai No. 551,154. (No model.)

T0 all whom it may concern:

a citizen of the United States, and a resident of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Revolving Swings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a side elevation of invention. Fig. 2 is a plan view of same. Fig. 3 is a section on line c a', Fig. 2, with seats, foot-boards, and their attachments removed. Fig. a is a plan view of mechanism for gripping and ungripping, clamp being loose and showing in dotted lines. Fig. 5 is a similar view with grip effected. Fig. 6 is a detail of clamp.

The object of this invention is to provide a revolving swing of simple construction and having means whereby it may be propelled by one or more of the riders; and the invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates a central standard or post, set securelyT in or rigidly secured to a suitable base, as I3.

O designates the swing proper, which is composed of a series of seats which are supported from an upper bearing, D, revoluble on said standard or post, and from a lower bearing, E, also on said standard or post.

The upper bearing, D, is shownas consisting of a sleeve which is itted to revolve upon the upper portion of the said post, being upheld by a collar or shoulder d. Attached to said sleeve is a plate D', to which are rigidly connected the upper ends of the arms F,which at their lower ends are firmly secured to the seat-frames or seats F. The lower bearing, E, also comprises a sleeve fitted to rotate upon the central post and bearing at its lower end upon a plate E', which is supported fromthe Be it known that I, GUsTAF H. CARLSON,

base around said post.

Attached to the sleeve E is a disk G, to which are secured radial arms II, which further support the seats. In the present instance I have shown the seats arranged in a series with a series of foot-boards alternating therewith, and seats and boards being con nected by the angle-irons I. I do not, hown ever, limit myself to any special form, arrangement, number, or construction of the seats or seat-frames, the arrangement described being nevertheless a very strong and convenient one.

J designates a sleeve which is revolubly seated around the central post intermediate of the upper and lower bearings and between a collar I' and a anged disk I2, both of which are rigidly secured to the post. Said sleeve J has a horizontally-projecting arm J near the outer end of which is a hollow vertical boss j, in which is loosely seated an axis or shaft K, which extends through the arm. On the lower end of this axis or shaft is a grip or clamp L, having a slot Z, which embraces the raised surrounding fiange t' of the disk I2. Rigidly secured to the upper portion of said shaft or axis is a lever M, whose longer arm projects over the seats and whose shorter arm is depressed and bent to form a pawl N, adapted to fit a portion of the sleeve J.

The operation of the swing is as follows, the direction of rotation being indicated by the arrow: Then the long arm of the lever is moved in the direction of the rotation of the swing, the pawl N takes a bearing against the sleeve J, which throws the slot l of the grip L into such position that its walls do not bind upon the walls of the flange t, and the said grip rides freely on the ange. When, however, the long arm of the lever is moved in the opposite direction, the walls of the slotZ at once bind upon the flange t' and the lever is locked firmly thereto. It will be understood, therefore, that the person or persons on the seat immediately behind the lever can, by pulling on the long arm thereof toward themselves, cause the swing to revolve in the opposite direction until they are brought up to the lever, when the latter is pushed in the ICO opposite ldirection to take a new grip on ythe flange t. This operation being repeated continuously, the swing is kept in rotation, the lever being alternately pulled and pushed in the ordinary manner of working a ratchet device.

' The herein-described swing is especially designed for family use, its size being small as compared with those which are operated by other than hand-power. It may, however, be made any size which can be operated by the means described. v

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a revolving swing, the combination with a central, non-rotary post, and with a swing-frame arranged to revolve thereon, of a sleeve,`J, loosely fitted upon an intermediate portion of the said post and having a projecting arm, a vertical shaft or'aXis journaled-in the lsaid arm an d having at its lower portion an integral grip, a lever attached to the said shaft or axis and having its handle portion extending outwardly in front of, and in position to'be grasped by the occupant or occupants of one of the seats, the other arm of said leverbeing arranged to take a bearing against the said sleeve, and a disk fast to said post and having a flange adapted to be engaged by the said grip, substantially as specified.

2. In a revolving swing, the combination with the central, non-rotary post, and the swing-frame arranged to revolve on the said post, of theloose sleeve J having the armA J,

the vertical shaft or axis K journaled in the said arm, and having at its lower end a slotted grip portion, a grip-flange fast to the said post, and a lever attached to the said shaft or axis, the shorter arm of said lever being shaped to form a pawl designed to fit partially around the said sleeve, whereby when the long arm of the said lever is moved in the direction of the rotation of the swing said pawl will engage the said sleeve, and thereby throw the grip into such relation to the gripflange that it slides freely thereon, substantially as specified.

3. In a revolving swing, the combination with a central, non-rotary post, of a swing havinga series of seats, a series of foot-boards arranged alternately of said seats, the angular irons I, the central portion-of each of the said irons being connected to one of `the seats and its end portions respectively to the footyboardsupon opposite sides of the said seat,

whereby said seats and boards are success'- ively united to each other and braced` the upper bearing-sleeve rotatably fitted upon said post, the series of arms connected to said sleeve and to the seats, the lower bearingsleeve, 'the series ofradial arms 4connected thereto and to the seats and the bearing-plate E for said lower sleeve, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
